Problems solved by technology

Therefore, the feedback control based on the deviation between the target number of revolutions and the actual number of revolutions of the motor cannot operate efficiently
On the other hand, in the case of performing simple feedforward control, since the sliding resistance differs depending on the mechanical annual change of the motor, vehicle seat, etc., and depending on the ambient temperature, there is a gap between the actual number of rotations of the motor and the target number of rotations. big difference
Therefore, the motor may stop unexpectedly due to insufficient torque

Embodiment Construction

[0053] One embodiment of the motor control device will be described below with reference to the drawings. The motor control device according to this embodiment controls the motor 30 based on the position of a driving target driven by the motor 30 and whose position can be changed according to the actuation of the motor 30 . Actuation targets include, for example, automatic doors of buildings, electric seats of vehicles, sliding doors, electric windows, and the like. Such as figure 1 As shown, the motor control device is configured as an electronic control unit 10 (hereinafter referred to as ECU 10 ) which is mainly provided with a central processing unit 11 (hereinafter referred to as CPU 11 ) as a core. The ECU 10 includes a program memory 12, a drive circuit 13, and the like. Programs serving as software executed by the CPU 11 are stored in the program memory. The drive circuit 13 converts the output of the CPU 11 , which is configured as a circuit generally operating var...

Abstract

The invention provides a motor control device 10 and a seat control device for vehicle with the motor control device. A motor control device (10) includes an acceleration portion (2) for increasing a target number of rotations (VT) of a motor (30) every predetermined calculation cycle until the target number of rotations (VT) of the motor (30) reaches an upper limit number of rotations (VL), which is set on the basis of a reached position of a driven object from a reference position, the driven object is driven by the motor (30) so that a position of the driven object is changed, a deceleration portion (4) for decreasing the target number of rotations (VT) of the motor (30) every calculation cycle after the target number of rotations (VT) reaches the upper limit number of rotations (VL), and a main control portion (1) for controlling a drive of the motor (30) on the basis of the target number of rotations (VT).

Description

technical field [0001] The present disclosure generally relates to a motor control device for controlling a motor that changes a position of a drive target. Background technique [0002] There are mechanisms for driving multiple and individual components by multiple motors to move them as a unit. For example, there is a vehicle seat whose state can be electrically switched between a sitting state allowing a user to sit on it and a storage state expanding a vehicle interior space by using a motor. An example of a power seat apparatus is disclosed in JP2007-62507A. The seat apparatus disclosed in JP2007-62507A is configured such that the state of the seat apparatus can be switched between a seated state and a storage state in accordance with a user's operation of an operation switch. More specifically, when the user continuously operates the operation switch, the seat cushion and the seat back are driven by corresponding motors, so that the state of the seat apparatus is swi...
